To aZLw/zom it concern:

Be it known that I, Gus'rar JOHNSON, a citizen of the United States,residing at Chicago, in the county of Cool: and State of Illinois, haveinvented certain new and useful Improvements in Carbureting Ap 'paratus,of which the following is a spccifition, strong, durable and eiiectivein opera.

tion, the parts of Which shall beso made and arranged'x vith respect toone another that a very small quantity of gasolcnc, which as is wellknown is highly explosive, will be contained in the machine and on thepremises,

yet it will be automatically supplied through the macliinein suificientor the. desircd.q-uan-- tities for carbureting.

, Another object of the invention is to provide improved means forcl'iarging air with thevolatilized hydro-carbons to the end thatilluminating carbureted air of the highest uality may be reduced orafl'orded, and so t aifl it may he eliveredj to thcservic'e pipes inaidry and pure condition and as required.

I Numerous other objects and advantages of. the invention will bedisclosed in the sub- .joined description and explanation.

. In order to enable others skilled in the art to which iny inventionpertains, to make and use the same, I will now proceed to describe it,referring to the accompanying drawings, in which Figure 1 is ave-rt-ical central sectional view of a carbureting apparatus embodyinthe invention;- *im 2 is a sectional view ta ten on linc'2-2 ot Fig. I'.looking in the directionindicated the arrows, showing a part otthe watertank and the air feeder or compressor located thercinyFig. 3 s ar'earend- View of the machine; F155. 4 is a front viewthereo Fig. 5 isan-en icw of a; ort'ion jo h irream or con'iprcssor,

. Like numerals of reference, refer to corresponding parts througl'routthe diflerent views of the drawings.

' The reference numeral 15' designates a tank which may he made of anysuitable size, form and .i'na'terial, but preferably of.

metal and: with its loner portion semicircular in shape. This tank. maybe mounted on supports 16, one of which is located nearend of a shaft 18which ishorizontally and longitudinally located in the. tank and has itsother end fitted in one end of a sleeve 19" which is rotatably mountedon a tubular shaft 20 which is journaleil in the opposite end of thetankfrom that to wlfiich the bearing 17 is secured. Extending from-theslccve'1'9'a nd' communicating with the cavity: thercof is a tube 21Which has-itsfreeen'd" open, as will be clearly understood b reference'to Fig. l of the drawings. 'ou'ntc'd" on the shaft 18 near each of itsends is'a! disk 22,,e'ach of which is provided with a scri'es of radialslots 23 to receive partitions 24 which. are radially disposed w threfer'- ence to the shaft 18 and in'su'ch a'nnai'n'rcr that their inneredges will be located at a slight distance from said shaft. Each of thepartitions 24 has at it's ends opPosit-cly extc-nded wings or flanges 25wine 1 will overlap each'othcr', yet 'w i ll be slightly spaced apart soas to permit the passage o'tl'a-ir' compartments 26 formed by thepartitions. Surrounding thepartitions 24 ands'ecuredto th'eir pc' inents26 between the flanges 25st sai end of the cylinder, it will be causedto enter the tube 21 and pass from the same into the airometer.

By reference to Fig. 1 it will be seen that the cylinder 27 of tie airfeeder or compressor, which is-designated as a whole by the referencenumeral 29, overlaps the. ends of the partitions 24 adjacent to the tube21,

' thus formin a chamber between the end 28 of the cylin er and theflanges 25' adjacent thereto. The rear upper portion of the tank .;lis'pr0. vided with a cover or housing 30 which extends to. about themiddle thereof and ha jour'naled on its up er front ortion .one en of ashaft 31 the ot er end 0 which, is journaled on a support 32 secured tothe front portion of thetank. This shaft has mounted thereon a drum 33,and is provided at its outer endwith means '34 to engage a crank when itisdesired to turn the drum in order to wind up the cable 35, which issecured at one of its ends to the drum and passes over a pulle 36suitably journaled on a hanger 37, an has at its other end a weight 38to actuate the drum 33 and through it and its gearing the air feeder 29.Mounted on the shaft 18 near its front end is a gear 39 which mesheswith a gearAO on one side of the.

, end of a pitman 4'9 which'is pivotally con nected at its lower end toa piston-rod which is pivotally secured, at its lower end to a pistonfillocated in a (pump cylinder 52, which 'pumpor cylin er communicatesthrough a coupling 53 with a valve-casin 54' which-is provide with aseries of v-a veseats 55 and 56, each having a, valvefi'? and 58respectively. 1 By reference to. Fig; '12 it will be se'en t at thevalve-se'ats5'5 are arranged below the support '53 whichcommunicateswith the pumping c linder '52,

" while the valves 56 and seatsterefor are,

located above the same.

The lower portion. of the vvalvecasing 54 has communication'through a 59with thevgasolene tank 60 which may located at any'suitable" point andat any distance from the machine or premises, and usually below thesurface of the.ground for the the cover 300i the water tan at portionofthe carbureter hasleadingtheresake of safety against explosion. f Theup per portion of the valve-casing 54, has coin- "niu'nication through apipe 61 and "a coupling 62' with ,the carburetor 63,- which 1s" ortionof,

preferably -vrnountedon the. upper i 1 ,ie ower;

zanyiisuitl amen) from a pipe 64 which also communicates with thegasolene tank 60, and is for the purpose of conveying the excess ofgasolene or oil to said tank.

As is clearly shown in Figs. 6 and 7 of the drawings, the carbureterconsists of a vessel of any suitable size, form and material, butpreferably of metal andi'rectangw,

\poztion an lar in shape, and has in its uppe inlet opening 65 for thesupply air thereto, as well as the opening or'coupling 62 for theadmission of gasolene. Located within the receptacle 63 are a series ofbattle-plates or. shelves 66 whichare alternately inclined in oppositedirections, as

shown, and each of said plates has its free end upturned as at 67to'form trou 'hs or receptacles to prevent the gasolene' tibwing fromsaid shelves or lates too rapidly, for it 'will be understood that saidplates or shelves extend from one side of the receptacle 63 to the otherside thereof and alternately from one end of the receptacle to near theother end thereof, thus roviding s aces between the alternate en s ofthe s ielves and the ends of the receptacle; 1 Each of the shelves 66 issupplied on its upper surface with a quantity of absorbent ma terial 68,such as felt, batting, asbestos or the like, to absorb and retaingasolene;

Suitably mounted near thecarburet'er 63 whole by the reference numeral69, and which consists of a vessel70 having its u per end open andprovided with a spout 1 through which water may be passed to saidvessel. The bottom of the vessel 70 has communication through a .pipe 72and a coupling 73 with the tubularshaft 20 of the air feeder, and saidcoupling may be rovidedwith a valve or cock 74 for-the ischarge ofwater. Extending upwardly from the bottom of the vessel 70 andcommunicating with the pipe 72 is a tube 75 which has in its upper end avalve-seat 76' for the valve 77 on the lowe end ofiarod 78 which dependscentrally from the to of a tank 79 which has itsbottom open an ismovably located in the vessel 70 so that the open end thereof will bese'aledby .the water contained in said vessel; The ower end of the tank79 is preferably provided with weights 80 secured thereto in ansuitable. manner. Communicatin Wltl the lower portion of the receptac e70.0f the airometer and usuall throu h the bottom is an airometer',which is indicatedas a thereof 'isa pipe 81 w ichleas to'and co1n'municates through. the coupling 65.

From the foregoin and by reference to the drawings it will %)6 readilyunderstood and clearly seen that, by 'su iplying water to the tank/15which may be one through a supply pipe 87 located in one end thereof iso that the water level will be at a point above the shaft 18, the airfeeder or compressor 29 may be caused to'rotate by reason of the actionof the weight 38, the cable 35, drum 33 and *earing between the shaft ofsaid drum and the shaft 18 on which the air compressor is mounted. Inthis operation it is apparent that in the rotation of the cylinder 27air will be caused to enter the con'ipartnients 26 of the compressorabove the water level and between the flanges :25 at that end of thecompressor adjacent. to the pum, As the compressor cylinder rotates fartier it will be understood that the air will pass from the compartmentwhich is l being, submerged into the chamber of the cylinder at the cndthereof in which the, tubeQl is. located between the flanges 25 and saidend, and will be' caused to enter the tube 21 andto pass therefrom intothe air-' ometer.

In the foregoinp operation the piston Ill of the pump will bereciprocatcd. thus alternatel v opening and closingthc valvcs ST and 5%,thereby drawing gasolcnc from the tank (it) through the pipe '51! intothe valve-casing 54, and from. thence through the pipe 01 into the-topof the carburetor where -it will fall onto thc upper battle-plate andpass operation it will be suspended b v reason ofthe tibstlllltfltmaterial located on said plates cnd'that' evaporation only air from theaironn-ler will at the same time be supplied to th carburetorthrouglrthe pipe 51, which, as before stated, leads from It is evidentthat the pump will be driven thrt'iugh the instrunh-ntality ol the gear40, pinion 4 pitinan it) and piston 51, which parts are actuated bv theweight 38, cable drum 1?
